Identifiable means that firms must be able to identify who is within their market to be able to design products or services to meet their needs.

This picture is of a Starbucks survey receipt, and if you fill out the receipt you receive a free drink. When you go to the website to fill out the survey they ask you questions that will help them identify who is within their market like your age, race, zip code, and how frequent you visit that store.
